Growing and Harvesting Bamboo in Vietnam
Vietnam Map Vietnam has an estimated 200,000 square miles of bamboo forests.
After Vietnam was defoliated by Agent Orange in the American War, bamboo was the first species to begin regenerating the forests.

Today, villagers in 29 provinces grow bamboo for domestic and export products.

An important bamboo for construction timber is bambusa stenostachya, or "tre gai", a clumping bamboo. Much of the tre gai bamboo comes from villages in Central Vietnam.

The tops of tre gai bamboo are used by chopstick factories, and the long, thick bottom poles usually ended up as scrap. Now Bamboo Technologies uses these sturdy, hard poles (10-14' long, 3"-4" diameter) to build houses.

Tre Gai Poles Bamboo growth cycle
New bamboo clumps mature enough to grow full size poles in about three years. In one three month spurt bamboo shoots reach full diameter and height, more than 60 feet high. In three years poles mature into dense, hard bamboo.

Harvesting bamboo at maturity is the critical first step to insure strong and durable quality poles. When bamboo poles reach peak strength and hardness, villagers in Central Vietnam harvest them. Bamboo clumps will grow new shoots for as many as 75 years.
